Exploring Rolling Mean and Return Rate of Gold Stock
We will include the most popular technical indicator moving average and exponential moving average (EMA) here. The Moving Average makes the line smooth and display the increasing or decreasing trend in price. Traders often use several different EMA days, for instance, 20-day, 30-day, 90-day, and 200-day moving averages.
Correlation Analysis
This analysis was done using % change to find how much the price changes compared to the previous day which defines returns. Knowing the correlation will help to see whether the returns are affected by other stocks’ returns
Stocks Returns Rate and Risk
Besides correlation, let’s analyze stock’s risks and returns by extracting the average of returns and the standard deviation of returns which is the risk associated. There could be causality associated showing the trend in the stock market and industry rather than showing how these stocks affect each other.

Reduced transaction costs.
What is trend-following algorithm?
The most common algorithmic trading strategies follow trends in moving averages, channel breakouts, price level movements, and related technical indicators. These are the easiest and simplest strategies to implement through algorithmic trading because these strategies do not involve making any predictions or price forecasts. Trades are initiated based on the occurrence of desirable trends, which are easy and straightforward to implement through algorithms without getting into the complexity of predictive analysis. Using 50- and 200-day moving averages is a popular trend-following strategy.
How does implementation shortfall strategy work?
The implementation shortfall strategy aims at minimizing the execution cost of an order by trading off the real-time market, thereby saving on the cost of the order and benefiting from the opportunity cost of delayed execution. The strategy will increase the targeted participation rate when the stock price moves favorably and decrease it when the stock price moves adversely.
What is delta neutral trading?

5 Reasons Why Stock Prediction Projects Fail
W ith the resurgence of machine learning and artificial intelligence, never has it been easier to implement predictive algorithms both new and old. With just a few lines of code, state of the art models can be readily accessible at the fingertips of the budding data enthusiast, ready to conquer whatever insurmountable digital task may lay at hand.
1. Selection Bias
Many projects start with the arbitrary selection of a stock with which an algorithm is to be applied to, this stock is often a tech stock such as Apple or Amazon, the simple reason being these companies are well known and ingrained in the everyday lives of consumers.
2. Portfolio Construction
Controlling risk is as important to a robust investment strategy as generating returns. If stock selection is the first part of the investment process, then portfolio construction is the vital next step.
3. Incorrect Application of Pre-processing
Standard rinse, wash and repeat data pre-processing techniques like standardization cannot be directly applied to stock prices. The below plot of the yearly distribution of S&P500 price levels should give some intuition as to why:
4. Look Ahead Bias
While nowadays it only takes a couple of lines of code to pull down a meaningful history of stock and macroeconomic fundamental data we need to be cognizant that this data is plagued with look ahead bias. Frequently, observations associated with particular dates would not have actually been available at that date.
5. The Project is Unfinished!
Many stock prediction projects will conclude like a regular machine learning project with the disclosure of a performance metric such as accuracy or RMSE with a line plot of the test vs training performance, reasoning that if the two lines are sufficiently close and the error reasonably low then the project was a success.
Conclusion
Before embarking on a stock prediction project, especially one that you intend to invest real money in, it pays to do some prior research on the subject and to understand the data.
